Authenticated change of media provided over a DSL connection

摘要

A method and system for fast channel changes of media that is provided by carriers over an xDSL connection to a hom. Each customer's subscriber information is stored at the DSLAM that supports the xDSL connection to the home. Also, each DSLAM supports multicast protocols so that only one instance of a channel is provided on the core network regardless of how many customers have requested access to the channel.
